Ajax在请求完成时没有回调

I'm uploading the image via AJAX but success is not calling on complete.

I have these 2 objects exits inside a form.

<img class="b_logo" id="b_logo_img" src="images/no_image.gif"> 
<input class="file_up" id="file_logo" type="file">

The data contain the URL for the image.

$(function() {

    $("#file_logo:file").change(function (){
       var fileName = $(this).val();
       savepic();
    });

});

function savepic()
{
var file_data = $("#file_logo").prop("files")[0]; // Getting the properties of file from file field
var form_data = new FormData(); // Creating object of FormData class
form_data.append("file", file_data) // Appending parameter named file with properties of file_field to form_data
form_data.append("user_id", 123) // Adding extra parameters to form_data
$.ajax({
url: "support_file/upload_image.php",
dataType: 'script',
cache: false,
contentType: false,
processData: false,
data: form_data, // Setting the data attribute of ajax with file_data
type: 'post',
success: function (data) {
$("#b_logo_img").attr("src",data);
}
});
}

    Removing the dataType: 'script' works.
